Product Information

The felt services we offer include: –

• New roofs (two and three-layer systems)
• Refurbishments
• Overlays

Each year, Guaranteed Asphalt carries out around 10-20,000 m2 of built up felt roofing in various configurations.

Each of our CE & BBA certified systems carry a product and installation guarantees of up to 25 years.

As well as our 25-year guarantee carrying built-up felt systems we also have fully bonded torch-on systems for concrete decks, a partially bonded system for warm roofs and a durable overlay system to give your old roof a new lease of life, complete with a 10-year guarantee.

Our range of membranes tested to perform at a range of temperatures from -5°C to -25°C and manufactured at our factory in Northamptonshire, are all supplied with heat sensitive film on the reverse to accurately gauge the correct amount of heat applied to the underside for the best possible bond and bleed. The cap sheets are heavy duty, mineral faced to guard against solar degradation, whilst the underlays are manufactured to the same high quality to ensure the same “feel” whilst installing.
